Steam Boiler Summer Shutdown

Hi everyone.

I browsed some threads and asked some people, but no definitive and simple answer...

How to shut down a residential steam boiler for the summer. Flush and drain it? Fill it up to the header? Do nothing? Other?...

Thanks!
Chris

Do nothing!

Do nothing, except continue to flush the boiler once a week or so. do not get out of the habit.

Keep flushing? Putting fresh water in without the boiler firing and cooking out all of the o2?

I don't know, but...That was that last thing I expected to hear!

Chris,
Flushing and adding fresh water to a boiler is never a good thing. The minerals alone from the fresh water will shorten the life of the boiler.
In my opinion that was bad advise and you should disregard.
The main thing with steam is to flush your low water cutoff if it is mechanical and that is to keep the float working properly and only a small amount. You can take a small amt out of the boiler maybe once a month in the winter to make sure the drawoff works.
If you want to check things in the summer you can check you pigtail that your pressuretrol is connected to. That will clog up over time. Remove that and make sure it's clear. Make sure your LWCO works and your site glass doesn't leak.
Of course if it's oil you should have it cleaned.
Other than that leave the boiler alone unless for some reason the water gets very dirty.

In a boiler be it steam or hot water FRESH WATER IS YOUR ENEMY.

Good Luck,

Ok cool. That makes more sense. I realize about the other things to look out for (leaks, pigtail, very dirty water, etc.). My main thing was just if it should be totally drained & empty for summer or still filled with water.

If I'm hearing you correctly it's the latter - Left with the water in it.

Thanks as always,
Chris
